You've gotten me farther along than I've been. Now I get a screen with a bottom 2/3rds blue background with a jagged top edge. Ten or so seconds after I turn on my video source, the top third fills with what kind of looks like large-blocky yellow lines of raster painting (lines which angle slightly downward). Might I ask what the commands you've provided do? v4l2-ctl -i 2 -- Tell the capture card to use the composite 1 jack as its input? sleep 2 -- wait 2 seconds for the capture card to settle down after switching inputs, before moving onto the next command. ivtv-tune -tus-bcast -c3 -- tune the card? to the US Broadcast band? on Channel 3? Why a separate set of utilities for controlling the card's tuner (ivtv-tune) separate from the set of utilities for controlling the card's input? Why do I have to specify the US-Broadcast band and channel 3; I thought composite input was "composite input" and not a tuned-channel input?
